The supplier section of Payaca is where you can save and manage any suppliers you use to source your materials.
Williams is the default supplier that is prepopulated into your account, however, you can add your own suppliers too.
The benefit of using Williams is that all their supplier data is automatically updated to Payaca. This means that all the prices and information for materials provided by Williams are always kept up to date with Williams' actual physical supply.
This saves you from having to manually update these prices and prevents you from accidentally mispricing a job.
If you do want to set up additional suppliers you can quickly upload new materials to these via a CSV import.
